If you're using WinXP, you can enable Complex Scripts and East Asian Language support under Regional and Language Options in the Control Panel :p Now when you pick a font in a program, any with a name beginning with "@" should contain a fair number of the symbols, but sideways - just remove the @ in front to get the version of the font with the symbols the correct way round :p
If you want more fonts, then off the top of my head, hongfire.com might be one place to check to find torrents of large batches of fonts with asian support, though I haven't checked recently so don't know if there's any current alive torrents for them or not :p
